5.Anger

4.Obesity

One of the major topics of recent surveys is the effect of genetic traits on the occurrence of obesity. The results of the studies established that though the weight of the students who were genetically predisposed to gain weight is similar to that of other children, they tend to quickly attain weight a few years later. So if you fall in that category of dieters where you put on weight with even a slight change in eating patterns, you are the unlucky few to have bad genes.

3.Lifespan

In recent years several studies have pointed to the fact that life expectancy can largely be dependent upon various genes.In 2009, a study at the Tokyo University of Agriculture found that a specific gene that was activated in men but not women, which backed up the fact why women on an average have a greater lifespan. The results of their research pointed to the conclusion that the gene allowed men to develop stronger bodies but at the cost of ageing. These studies and others like them show that lifespan may be strongly dependent on your genetic makeup, although it is affected by a number of genes. Instead of cursing your family hand reader, blame your genes for your short lifeline!

2.The pessimist effect

A new study by UCLA life scientists found that the oxytocin receptor gene is a strong predictor of optimism and self-esteem. Apparently if certain nucleotides at specific locations on the gene are absent you are more likely to be an optimist. Other scientists claim that a different gene regulates the neurotransmitter serotonin, that is the "happy hormone." So with the results of the survey it comes as a surprise that your mood may not be as much under your control as you thought and not always linked to environmental factors. Some people are just happy! If you're one of those people who look at the glass half empty, it may not just be you but your genes acting out which may be one of the reasons to be happy that your state of mind is not some kind of a weakness.

1.Addiction to Cigarette Smoking

According to an article printed in the Washington post, scientists have managed to pinpoint variations in the genetic make-up of people which make them more prone to getting addicted to cigarettes. This discovery makes an irrefutable case backing up the role of your genetic structure to nicotine addiction. Christopher Amos, a professor of epidemiology at the M.D. Anderson Cancer Center in Houston and author of one of the studies said and I quote, "It also makes you more likely to be dependent on smoking and less likely to quit smoking." Based on these studies, it is reported that these smokers on an average light up two extra cigarettes a day and find it much more difficult to give up smoking.
